Figure 4. ZNRF3 gene was identified as a direct target of miR-146a.
(A) 6 target genes of miR-146a were identified by miRNA forecasting software. (B) Diagrams demonstrated the miR-146a putative binding sites and corresponding mutant sites of ZNRF3. (C) The expression levels of ZNRF3 were examined after transfection with miR-146a by qRT-PCR and Western blotting assays in MG-63 and HOS cells. (D) Luciferase activity of ZNRF3 (wild type or mutation) was evaluated after miR-146a transfection into MG-63 and HOS cells. **P<0.01.
